YT-70AB Automatic Water Pump Controller

Intelligent Water Level Control System for Efficient Pump Automation

Product Overview

The YT-70AB Automatic Water Pump Controller is a high-performance, intelligent control solution designed to automate water pump operations based on water level detection. Engineered for reliability and precision, this controller ensures efficient water management by automatically starting and stopping the pump—eliminating manual intervention and reducing operational risk.

Ideal for residential, commercial, and industrial water systems, the YT-70AB enhances pump lifespan, prevents dry running, and optimizes water usage with consistent performance.

Key Features

Fully Automatic Operation

Automatically controls pump ON/OFF based on water levels—ensuring seamless water supply and drainage without manual monitoring.

Dual-Level Water Detection

Equipped with high and low water level sensing (L1 & L2), enabling precise control of tank filling and drainage cycles.

Wide Voltage Compatibility

Supports AC/DC 24V–220V, making it suitable for diverse electrical environments and installations.

Durable & Long-Life Performance

• Mechanical life: 10 million operations
• Electrical life: 10 million operations
  Built for long-term, consistent operation in demanding conditions.

Anti-Dry Run Protection

Automatically stops the pump when water levels are low—protecting the pump from damage and extending service life.

Corrosion-Resistant Design

Ventilated housing structure minimizes moisture accumulation and protects internal components from corrosion.

Flexible Installation

Supports vertical mounting with adjustable float ball positioning for customized water level control.

Working Principle

The YT-70AB operates using a float-based sensing mechanism:

• When water level drops → float descends → controller activates pump
• When water reaches upper limit → float rises → controller stops pump

This intelligent switching ensures:

• Continuous water availability
• No overflow or dry running
• Stable and automated system control

For drainage systems, the logic is reversed—automatically removing excess water when levels rise.

Technical Specifications

For pumps above 0.75kW, use with an external AC contactor.
